load_nls() take a char * parameter, use it to find nls module in list or
construct the module name to load it.
This change make load_nls() take a const parameter, so we don't need do
some cast like this:
ses->local_nls = load_nls((char *)ctx->local_nls->charset);

Pull tracing fixes from Steven Rostedt:
- Fix to /sys/kernel/tracing/per_cpu/cpu*/stats read and entries.
If a resize shrinks the buffer it clears the read count to notify
readers that they need to reset. But the read count is also used for
accounting and this causes the numbers to be off. Instead, create a
separate variable to use to notify readers to reset.
- Fix the ref counts of the "soft disable" mode. The wrong value was
used for testing if soft disable mode should be enabled or disable,
but instead, just change the logic to do the enable and disable in
place when the SOFT_MODE is set or cleared.

mm->mm_lock_seq effectively functions as a read/write lock; therefore it
must be used with acquire/release semantics.
A specific example is the interaction between userfaultfd_register() and
lock_vma_under_rcu().
userfaultfd_register() does the following from the point where it changes
a VMA's flags to the point where concurrent readers are permitted again
(in a simple scenario where only a single private VMA is accessed and no
merging/splitting is involved):
userfaultfd_register
userfaultfd_set_vm_flags
vm_flags_reset
vma_start_write
down_write(&vma->vm_lock->lock)
vma->vm_lock_seq = mm_lock_seq [marks VMA as busy]
up_write(&vma->vm_lock->lock)
vm_flags_init
[sets VM_UFFD_* in __vm_flags]
vma->vm_userfaultfd_ctx.ctx = ctx
mmap_write_unlock
vma_end_write_all
WRITE_ONCE(mm->mm_lock_seq, mm->mm_lock_seq + 1) [unlocks VMA]
There are no memory barriers in between the __vm_flags update and the
mm->mm_lock_seq update that unlocks the VMA, so the unlock can be
reordered to above the `vm_flags_init()` call, which means from the
perspective of a concurrent reader, a VMA can be marked as a userfaultfd
VMA while it is not VMA-locked. That's bad, we definitely need a
store-release for the unlock operation.
The non-atomic write to vma->vm_lock_seq in vma_start_write() is mostly
fine because all accesses to vma->vm_lock_seq that matter are always
protected by the VMA lock. There is a racy read in vma_start_read()
though that can tolerate false-positives, so we should be using
WRITE_ONCE() to keep things tidy and data-race-free (including for KCSAN).
On the other side, lock_vma_under_rcu() works as follows in the relevant
region for locking and userfaultfd check:
lock_vma_under_rcu
vma_start_read
vma->vm_lock_seq == READ_ONCE(vma->vm_mm->mm_lock_seq) [early bailout]
down_read_trylock(&vma->vm_lock->lock)
vma->vm_lock_seq == READ_ONCE(vma->vm_mm->mm_lock_seq) [main check]
userfaultfd_armed
checks vma->vm_flags & __VM_UFFD_FLAGS
Here, the interesting aspect is how far down the mm->mm_lock_seq read can
be reordered - if this read is reordered down below the vma->vm_flags
access, this could cause lock_vma_under_rcu() to partly operate on
information that was read while the VMA was supposed to be locked. To
prevent this kind of downwards bleeding of the mm->mm_lock_seq read, we
need to read it with a load-acquire.
Some of the comment wording is based on suggestions by Suren.
BACKPORT WARNING: One of the functions changed by this patch (which I've
written against Linus' tree) is vma_try_start_write(), but this function
no longer exists in mm/mm-everything. I don't know whether the merged
version of this patch will be ordered before or after the patch that
removes vma_try_start_write(). If you're backporting this patch to a tree
with vma_try_start_write(), make sure this patch changes that function.

"Constify thermal_zone_device_register() parameters, which was omitted

Since commit 3d439b1a2ad3 ("thermal/core: Alloc-copy-free the thermal zone
parameters structure"), thermal_zone_device_register() allocates a copy
of the tzp argument and callers need not explicitly manage its lifetime.
This means the function no longer cares about the parameter being
mutable, so constify it.
No functional change.

Note that these functions are essentially just leftovers from the first
iteration of the wake-irq implementation where device drivers were
supposed to call these functions themselves instead of PM core (as
is also indicated by the bogus kernel doc comments).

Xen 4.17 supports the creation of static evtchns. To allow user space
application to bind static evtchns introduce new ioctl
"IOCTL_EVTCHN_BIND_STATIC". Existing IOCTL doing more than binding
that’s why we need to introduce the new IOCTL to only bind the static
event channels.
Static evtchns to be available for use during the lifetime of the
guest. When the application exits, __unbind_from_irq() ends up being
called from release() file operations because of that static evtchns
are getting closed. To avoid closing the static event channel, add the
new bool variable "is_static" in "struct irq_info" to mark the event
channel static when creating the event channel to avoid closing the
static evtchn.
Also, take this opportunity to remove the open-coded version of the
evtchn close in drivers/xen/evtchn.c file and use xen_evtchn_close().

syzkaller found a warning in packet_getname() [0], where we try to
copy 16 bytes to sockaddr_ll.sll_addr[8].
Some devices (ip6gre, vti6, ip6tnl) have 16 bytes address expressed
by struct in6_addr. Also, Infiniband has 32 bytes as MAX_ADDR_LEN.
The write seems to overflow, but actually not since we use struct
sockaddr_storage defined in __sys_getsockname() and its size is 128
(_K_SS_MAXSIZE) bytes. Thus, we have sufficient room after sll_addr[]
as __data[].
To avoid the warning, let's add a flex array member union-ed with
sll_addr.
Another option would be to use strncpy() and limit the copied length
to sizeof(sll_addr), but it will return the partial address and break
an application that passes sockaddr_storage to getsockname().

For both IPv4 and IPv6 incoming TCP connections are tracked in a hash
table with a hash over the source & destination addresses and ports.
However, the IPv6 hash is insufficient and can lead to a high rate of
collisions.
The IPv6 hash used an XOR to fit everything into the 96 bits for the
fast jenkins hash, meaning it is possible for an external entity to
ensure the hash collides, thus falling back to a linear search in the
bucket, which is slow.
We take the approach of hash the full length of IPv6 address in
__ipv6_addr_jhash() so that all users can benefit from a more secure
version.
While this may look like it adds overhead, the reality of modern CPUs
means that this is unmeasurable in real world scenarios.
In simulating with llvm-mca, the increase in cycles for the hashing
code was ~16 cycles on Skylake (from a base of ~155), and an extra ~9
on Nehalem (base of ~173).
In commit dd6d2910c5e0 ("netfilter: conntrack: switch to siphash")
netfilter switched from a jenkins hash to a siphash, but even the faster
hsiphash is a more significant overhead (~20-30%) in some preliminary
testing. So, in this patch, we keep to the more conservative approach to
ensure we don't add much overhead per SYN.
In testing, this results in a consistently even spread across the
connection buckets. In both testing and real-world scenarios, we have
not found any measurable performance impact.

VXLAN-GPE does not add an extra inner Ethernet header. Take that into
account when calculating header length.
This causes problems in skb_tunnel_check_pmtu, where incorrect PMTU is
cached.
In the collect_md mode (which is the only mode that VXLAN-GPE
supports), there's no magic auto-setting of the tunnel interface MTU.
It can't be, since the destination and thus the underlying interface
may be different for each packet.
So, the administrator is responsible for setting the correct tunnel
interface MTU. Apparently, the administrators are capable enough to
calculate that the maximum MTU for VXLAN-GPE is (their_lower_MTU - 36).
They set the tunnel interface MTU to 1464. If you run a TCP stream over
such interface, it's then segmented according to the MTU 1464, i.e.
producing 1514 bytes frames. Which is okay, this still fits the lower
MTU.
However, skb_tunnel_check_pmtu (called from vxlan_xmit_one) uses 50 as
the header size and thus incorrectly calculates the frame size to be
1528. This leads to ICMP too big message being generated (locally),
PMTU of 1450 to be cached and the TCP stream to be resegmented.
The fix is to use the correct actual header size, especially for
skb_tunnel_check_pmtu calculation.

Xiang reports that VMs occasionally fail to boot on GICv4.1 systems when
running a preemptible kernel, as it is possible that a vCPU is blocked
without requesting a doorbell interrupt.
The issue is that any preemption that occurs between vgic_v4_put() and
schedule() on the block path will mark the vPE as nonresident and *not*
request a doorbell irq. This occurs because when the vcpu thread is
resumed on its way to block, vcpu_load() will make the vPE resident
again. Once the vcpu actually blocks, we don't request a doorbell
anymore, and the vcpu won't be woken up on interrupt delivery.
Fix it by tracking that we're entering WFI, and key the doorbell
request on that flag. This allows us not to make the vPE resident
when going through a preempt/schedule cycle, meaning we don't lose
any state.

Before removing checkpoint buffer from the t_checkpoint_list, we have to
check both BH_Dirty and BH_Lock bits together to distinguish buffers
have not been or were being written back. But __cp_buffer_busy() checks
them separately, it first check lock state and then check dirty, the
window between these two checks could be raced by writing back
procedure, which locks buffer and clears buffer dirty before I/O
completes. So it cannot guarantee checkpointing buffers been written
back to disk if some error happens later. Finally, it may clean
checkpoint transactions and lead to inconsistent filesystem.
jbd2_journal_forget() and __journal_try_to_free_buffer() also have the
same problem (journal_unmap_buffer() escape from this issue since it's
running under the buffer lock), so fix them through introducing a new
helper to try holding the buffer lock and remove really clean buffer.

Pull networking fixes from Jakub Kicinski:
"Including fixes from BPF, netfilter, bluetooth and CAN.
Current release - regressions:
- eth: r8169: multiple fixes for PCIe ASPM-related problems
- vrf: fix RCU lockdep splat in output path
Previous releases - regressions:
- gso: fall back to SW segmenting with GSO_UDP_L4 dodgy bit set
- dsa: mv88e6xxx: do a final check before timing out when polling
- nf_tables: fix sleep in atomic in nft_chain_validate
Previous releases - always broken:
- sched: fix undoing tcf_bind_filter() in multiple classifiers
- bpf, arm64: fix BTI type used for freplace attached functions
- can: gs_usb: fix time stamp counter initialization
- nft_set_pipapo: fix improper element removal (leading to UAF)
Misc:
- net: support STP on bridge in non-root netns, STP prevents packet
loops so not supporting it results in freezing systems of
unsuspecting users, and in turn very upset noises being made
- fix kdoc warnings
- annotate various bits of TCP state to prevent data races"

The btmtk driver uses an IS_ENABLED() check to conditionally compile
the coredump support, but this fails to build because the hdev->dump
member is in an #ifdef:
drivers/bluetooth/btmtk.c: In function 'btmtk_process_coredump':
drivers/bluetooth/btmtk.c:386:30: error: 'struct hci_dev' has no member named 'dump'
386 | schedule_delayed_work(&hdev->dump.dump_timeout,
| ^~
The struct member doesn't really make a huge difference in the total size,
so just remove the #ifdef around it to avoid adding similar checks
around each user.

hci_update_accept_list_sync iterates over hdev->pend_le_conns and
hdev->pend_le_reports, and waits for controller events in the loop body,
without holding hdev lock.
Meanwhile, these lists and the items may be modified e.g. by
le_scan_cleanup. This can invalidate the list cursor or any other item
in the list, resulting to invalid behavior (eg use-after-free).
Use RCU for the hci_conn_params action lists. Since the loop bodies in
hci_sync block and we cannot use RCU or hdev->lock for the whole loop,
copy list items first and then iterate on the copy. Only the flags field
is written from elsewhere, so READ_ONCE/WRITE_ONCE should guarantee we
read valid values.
Free params everywhere with hci_conn_params_free so the cleanup is
guaranteed to be done properly.
This fixes the following, which can be triggered e.g. by BlueZ new
mgmt-tester case "Add + Remove Device Nowait - Success", or by changing
hci_le_set_cig_params to always return false, and running iso-tester:

We will remove this restriction in llc_rcv() in the following patch,
which means that the protocol handler must be aware of netns.
if (!net_eq(dev_net(dev), &init_net))
goto drop;
llc_rcv() fetches llc_type_handlers[llc_pdu_type(skb) - 1] and calls it
if not NULL.
If the PDU type is LLC_DEST_CONN, llc_conn_handler() is called to pass
skb to corresponding sockets. Then, we must look up a proper socket in
the same netns with skb->dev.
llc_conn_handler() calls __llc_lookup() to look up a established or
litening socket by __llc_lookup_established() and llc_lookup_listener().
Both functions iterate on a list and call llc_estab_match() or
llc_listener_match() to check if the socket is the correct destination.
However, these functions do not check netns.
Also, bind() and connect() call llc_establish_connection(), which
finally calls __llc_lookup_established(), to check if there is a
conflicting socket.
Let's test netns in llc_estab_match() and llc_listener_match().
